HEDDLE BAR LocK 1 Figled April 30. 1945 2 Sheets-Sheet 2 Patented Oct. 22, 1946 UNITED STATES PATENT OFFICE HEDDLE BAR LOCK David Edward Buice, VSr., Ellenwocd, `(la.` Application April 30, 194.5," Serial No." 591-3007 4 Claims.

:This inventionlrelatesvto heddle bar locking structures for use-in retaining heddle bars in heddle frames.

'The principal `object of this invention is the provision-of new and improved locking elements for heddle bars. of heddle bar locks which may be readily replaced in the event that the lock becomes inoperative due to wear in use. A still further object is the provision of heddle bar locking elements which may be removed or replaced without the removal or dismemberment of the other members oi the heddle frame. Other objects are the provision of heddle frameharness ends possessing new and improved heddle bar locking structures and the provision of heddle frames including new and improved heddle bar locks which permit the elements of the locks which receive the most Wear during use to be readily replaced. Further objects and the entire scope of this invention will come apparent from the detailed description given hereinafter.

These objects are accomplished according to my invention by a unique combination and arrangement of parts of heddle bar locking elements and heddle frame elements which comprise a removable locking pin and an element for retain- A further object is the provision ing the locking pin in position in the heddle frame as more fully described below.

Referring to the drawings:

Figure 1 is a fragmental elevation of a heddle frame embodying the use of this bar lock.

Figure 2 is an end elevational view of the same.

Figure 3 is a fragmental elevation of the heddle frame, illustrating the heddle bars released and moved laterally to permit removal of the heddles.

Figure 4 is an enlarged view of the outer face of the harness end piece.

Figure 5 is a similar enlarged view from 'the inner face thereof.

Figure 6 is a perspective view of its locking structure.

Figure 7 is a perspective View of locking pin detached.

Referring to the drawings in detail, the heddle frame is composed of lower and upper bars I supplied with the usual heddle bar securingmembers 2 to which the heddle bars 3 are connected. The heddle bars 3 are held in spaced parallel relation with each other and with the bars I by means of the harness end pieces 4 which have inwardly extending ends 5. The harness end pieces 4 are secured to the frame bars I by means of screws 6 extending through the inwardly extended ends 5.

The parallel spaced heddle bars'3 support the frame bars I by lmeans of the harness end pieces 4by extension through the openings 9 provided therefor in the end pieces 4. The heddle bars 3are provided at their ends with openings III to receive the locking pin II of the locking element of my invention, which permit the heddle bars to be securely held against movement relative to the harness ends 4.

The locking structures of my invention consist of a combination of a lock pin I I and a securing elementu IZ. The securing spring element I2 is held in place in the harness end piece 4 at one end by providing this end I3 of the spring with a bend permitting the spring to extend through the holes I4 and I5 of the harness piece 4. The spring I2 is provided at the end opposite to the curved'end I3 with a short, hook-like bend I5 extending at right angles to the major extension of the spring I2 and the end member 4 when the spring is positioned in the end member 4.

The locking pin I I is provided at one end with an opening il of suiiicient size to permit this end to be slipped over and about the spring element l2. In operation, the pin II extends through the openings Ii) in the heddle bars 3 and. is securely held in this position by the spring I2 which in turn, is secured against movement relative to the harness piece 4 by the spring action operating between the secured end I3 of the spring extending through the holes I4 and I5 in the harness piece 4 and the hook end I6 hooked over the edge of the piece 4.

The principal point of friction and wear in a heddle frame is at the holes I0 in the ends of the heddle bars 3 and on the portion of the heddie bar locking structure extending through these holes. In order to replace the worn portion of a heddle lock when my type of lock is employed in the heddle frame, the replacement may be accomplished rapidly and without removal of any portion of the locking element permanently fastened to the harness end 4. Thus, the only portion of the locking element of my invention requiring replacement upon Wear is the locking pin I I. This pin is readily removed and replaced by unhooking the spring I2 from the harness end 4 by moving the spring suiciently to disengage the hook end I 6 from the harness end 4, and then forcing the spring a suincient distance in the opposite direction to permit the pin II to be removed from the holes I0 in the heddle bars 3 and be removed from the spring I2. A new pin is then placed upon the spring, inserted through to holes I0 of the heddle bars 3 and locked into place by hooking the end I6 over the harness end 4.

Having thus described my invention, what I claim is:

1. A heddle bar locking structure comprising a pin adapted to movably extend through the end opening in a heddle bar, said pin being provided with an aperture in one end thereof, and an element for securing said pin against movement out of said bar-end openings comprising a spring wire element including a substantially straight portion adapted to extend through the aperture in the pin, one end of the wire element being angled to releasably engage the harness end of a heddle frame and the opposite end of the Wire element being adapted to be secured to said harness end.

2. A heddle bar frame member comprising a heddle frame harness end and a heddle bar locking structure connected thereto said locking structure comprising a pin adapted to be extended through the end opening in a heddle bar said pin possessing an opening in an end thereof, and a pin securing element extended through said pin opening, said securing element constituting a spring wire fastened at one end to said harness end and including an angled portion with a hooked end at the opposite end adapted to releasably engage said harness end.

3. A heddle bar frame comprising upper and lower bars, harness ends for holding the upper and lower bars in spaced relation With each other, heddle bars supported by the upper and lower bars, said harness ends having openings to receive the ends of said heddle bars to removably mount the heddle bars on the harness ends, a pin inserted through openings in the ends of said heddle bars securing the heddle bars against movement, and a wire spring element extending through an aperture in the end of said pin securing said pin from movement out of said bar openings, said Wire element being fastened at one end to said harness end and releasably engaged at the opposite end to said harness end by an angled portion including a hooked end.

4. A heddle bar locking structure comprising a pin adapted to extend normally through the end opening in a heddle bar, said pin being provided With an aperture in one end thereof, said pin being removable from said bar-end openings and from the other elements of said locking structure, and an element for securing said pin against movement out of said bar-end openings comprising a spring wire element including a straight portion adapted to extend through the aperture in the pin normally to the heddle bar, the wire element being adapted to engage the harness end of a heddle frame.
